Be it known that i, DAviD F. B Ronnnioir, e citizen'oi the United States, residing et New Britain, county of Hertford, State of Connecticut, have invented certain .new and useful Improvements-in Rotary Brushes, of

which tlefllowing is e full, clear, end exact description.

My invention relates to rotary brushes, particularly driven by power.

Tite object is to provides brush in which. the bristles may be readily replaced und to Wlicli one or more iluids or pastes inay be supplied while tle brush is in operation and controlled in amount as desired.

Anotl: er object is to prevent abrasion in the bearings.

'l`le orinci les t tli i ei ti n are. illusl p o e nv i o tinted in the seeoinpenying single sheet otl drawings. it contemplates tl'e employment of n cylindrical Core formed of metallic seginents carrying` removable bristles. "Fee/(1P pipes lend through eaeli end of the core Jfor supplying the fluid to be used.

l1 igure l is n longitudinal sectional view oi :i oonstruetioi'i embodying my invention. Fig. 2 is zt cross-sectional view of' ii. core und bristles.

21 and 22 are outlets from the supply-v pipes Within thc eliainber or reservoir formed .in tlie core. I,

By this oonstruetion any lluid or pti-ste which will How may bc supplied in iiiiy quantity to the interior ol. the brush Lind will be delivered to the root of the bristles sind iipplied directly to the surface being; operated upon without waste or simttering. W'hen any of the bristles bcooiue worn out Vor injured, one of't ie eoreescgnients may be reinoyed sind u. new one substituted or the bris# tlcs repaired or replneed'without interfering with the rest oi the nuichine, thus saving; time rind niouey.

The invention is psrtioulairly intended for use in inechil'ies for finishing;- and polishingr hardware, such us locks, eseutchoons, 6to. In suoli work puiniec-stone is used frequently. For this reason the leed-pipes 14 und 15 are spneed eport frein the spindles und il, so tliatt-the ports cannot Contact with ezt-eli otl.ici`'wliere there yis any likelihood oi' uninsion.

T he advantages oi this construction will be apparent to those skilled in the nrt.A
